Well, the idea behind this script is to auto-tune some of the 
postgresql.conf settings based on the actual hardware and of course 
based on the expected workload.

There are two different jobs to do:

- Determine the current hardware confiuguration (number and speed of 
cpu's, ram size, i/o, number of disks, network, ...)
- Ask the user - or even better, trace the database - about the expected 
workload (reads, writes, mixed workload, oltp, data warehouse, number of 
concurrent connections and queries, used ram for queries and cache, and 
so on)

I think, Perl or Python is a choice of the author, whatever he knows 
best. Of course, it would be helpful, if such a script (or collection of 
scripts) would use the same scripting language than all the current 
scripts in the PostgreSQL source.

Hope, this helps
